BUTTER-HOLDER FQR BUTTER-DISHES.

SPECIFICATION forming part of Letters Patent No. 226,666, dated April20, 1880.

Application filed March 13, 1880. (N0 model.)

To all whom it may concern Be it known thatI, WILLIAM R. IVIACKAY, ofMeriden, county of New Haven, State of Connecticut, havefinventedcertain new and useful Improvements in Butter-Holders for Butter-Dishes;and I hereby declare that the following is a full, clear, and exactdescription and specification of the same, reference being had to theaccompanying drawings, making part thereof.

My invention relates to means for securing the disk, of glass or suchlike material, forming the bottom of the movable butter-holder of abutter-dish, so that it may be easily and readily removed for thepurpose of cleansing it.

The glass plate has heretofore been fastened permanently in the flangedrim of the butter-holder, or laid loosely in some such holder, in whichcase it is liable to be lost or broken.

My invention consists in certain combinations of parts or elements setforth specifically in the claim at the end of this schedule.

In order that persons skilled in the art may understand, make, and usemy improvements, I will proceed to describe the same, referring to thedrawings herewith, in whieh- Figure l is a top view of my movablebutter-holder, showing the glass bottom piece centrally located in it,surrounded by drip-holes in the flanged rim. A part of this flanged rimis broken away to show a horizontal part section of the flange whichsurrounds the glass bottom plate, and also the fastening and holdingpiece outside and under it. Fig. 2 is a part side view and part sectionof the same on line a r, Fig. 1, showing the glass bottom B notsectioned. Fig. 4 is a bottom view, with a small part of the flangesurrounding the glass bottom and the holding-ring in horizontal section.Fig. 3 is a part side View and part section on a vertical diameter lineof another t'orm of holdil'ig-piece.

The same letters of reference indicate like parts in the differentfigures.

a is the flanged rim of my movable butterholder; B, the glass bottomplate C, the flange, projecting below the body a and fixed to it, of adiameter larger than the hole in a,

so as to leave a slight horizontal projection above the glass bottomplate to hold it from rising out of its position. Flange C extendsdownward about the thickness of the glass bottom plate, B.

D is the fastening-ring, which shuts over and around the flange C, towhich it is fastened by means of the slot H in ring D and pin F inflange C. This holding-piece may have an opening in its bottom, as shownin Fig. 4, leaving only a slight shoulder, J, to hold the glass inplace, or it may be made solid without any opening, as in Fig. 3, inwhich case the bottom may be engraved or embossed with figures ordesigns on its inner surface.

The holes 9 g g in the flat surface of the rim a outside of the flange Care drip-holes to carry water below the glass bottom plate and keep thebutter dry.

My movable butter-holder with its glass bottom attached is designed tobe placed within a butter-dish case, which case is not shown.

The glass bottom presents a hard surface for thebutter to rest upon, sothat in cutting the butter the bottom will not be cut or marred, as inthe case of a metal bottom.

When the glass bottom is permanently fastened to the movablebutterholder butter gets in between the metal plate and glass, and thesalt from the butter oxidizes the metal; but by my construction the twocan be separated and washed, so that no oxidation need take place.

Having now fully described. my improvements and the manner in which Ihave embodied them, what I claim as my invention, and desire to secureby Letters Patent, is

In the movable butter-holder ot' a but-terdish, the combination,substantially as hereinbefore set forth, of the rim a, provided with adownwardly-projecting flange surrounding a glass bottom plate, and theremovable fastening ring or piece, all constructed and arranged tooperate in the manner and for the purposes set forth.

WILLIAM R. MACKAY.
